Agreed. The problem here is that one of Bob's 'pseudo-residue fragments'
spans across residues that are considered part of 2 molecules (according to
SOLVENT_POINTERS and ATOMS_PER_MOLECULE). It's likely that this happened
because of an "improperly" create topology file. Of course, how exactly he
split the workload in pmemd is not something I put sufficient amount of time
into understanding, so I don't know the machinery behind it.

Specifically what we need here, though, is the details of EXACTLY how you
created your topology file.

All the best,
Jason
